Summary:Objective To investigate the influencing factors of 1-year postoperative mortality in elderly patients with hip fracture based on new nutritional indicators, and draw a predictive nomogram for 1-year death in these elderly patients. Methods A retrospective study was conducted on 457 elderly hip fracture patients who underwent surgical treatment in our department from January 2018 to May 2021. All of them were followed up, and the outcomes in 1 year after operation were observed. Their baseline data, mini-nutritional assessment (MNA) score, nutritional risk screening 2002 (NRS2002) score, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, serum nutritional indicators, body compositions and other new nutritional indicators were collected and analysis with 1-year mortality as observation outcome. Multivariate logistic regression analysis was used to analyze the independent risk factors of 1-year postoperative death in these elderly patients, and further R Studio software was applied to build a no
